46 of 52 explained

Water solvent

Water is the base almost every serum, toner and cream is built on. It dissolves the water-loving ingredients and sets how light the finished texture feels. On an INCI list it is usually first, which only means it is the largest single ingredient by weight.

Dipropylene Glycol humectant

Dipropylene Glycol is a glycol used as a solvent and a light humectant. Its main job is keeping the rest of the formula dissolved and the texture fluid rather than adding hydration of its own.

Xylitol humectant

Xylitol is a sugar alcohol humectant. It holds water in the outer layer of skin and is often paired with anhydroxylitol and xylitylglucoside as a hydration trio.

Alcohol solvent

Alcohol here means ethanol. It dissolves ingredients water cannot, evaporates fast so a formula sets quickly and does not feel heavy, and thins texture. In quantity it can leave dry or reactive skin feeling tight, which is why many Korean formulas avoid it and some deliberately use it for a fast, weightless finish.

PEG-60 Hydrogenated Castor Oil emulsifier

PEG-60 Hydrogenated Castor Oil is a castor-oil-derived solubiliser. It is what keeps fragrance and oil-soluble ingredients dissolved in a watery formula so it stays clear.

Polyacrylamide film former

A polymer used to thicken and to hold an emulsion together. It leaves a light film that helps a formula stay put.

Dimethicone/Vinyl Dimethicone Crosspolymer silicone

This is a silicone elastomer, a soft springy gel. It fills the look of fine texture and gives the velvety, blurred finish of a primer.

Phenoxyethanol preservative

Phenoxyethanol is the most widely used cosmetic preservative outside the paraben family. It keeps a water-containing formula from growing bacteria and mould, and is capped at one percent in most markets, so it always sits low on a list.

C13-14 Isoparaffin emollient

A light branched hydrocarbon, usually part of the thickener system in a lotion. It gives a smooth, quick-spreading feel.

Triethanolamine pH adjuster

Triethanolamine is an alkaline base used to neutralise acidic gelling agents such as carbomer. Once neutralised the gel thickens, which is what holds a clear gel together.

Salicylic Acid exfoliant

Salicylic Acid is a BHA, and the only common exfoliant that is oil soluble, so it can work inside a pore rather than only on the surface. It loosens the dead cells that block pores and is used for the look of congested, oily skin.

Carbomer thickener

Carbomer is a synthetic polymer that only gels once a base neutralises it, which is why arginine or tromethamine sits nearby on the list. It gives the clear, non-stringy gel texture a xanthan formula cannot reach.
